在过去的几年中，建筑业受到了严重的批评和自我分析。两项研究，一项由内多（Nedo）组成的研究，另一项研究有限，尤其是，尤其是因为它们是特定的。两者都发现，从构想到建筑物的执行，行业与其他国家的比较很差。建筑物和工程EDC'S-'建筑行业的职业的另一项调查主要基于访谈，并包含许多关于缺点的意见3，并提出许多主题进行进一步研究。
焊接的设计的理论背景plate girders according to BS449 is adopted in a search for optimum design. Within certain practical limitations, design curves are derived for minimum weight design. A computer-based design system is described from which minimum cost designs can be produced for conventional plate girders and welded crane girders. Some observations derived from computer results are given which, together with the design curves, provide guidelines to wards obtaining an optimum design. G.C. de Jesus and A. Burns
在许多思想中，结构工程似乎仅限于结构系统的概念和分析以及详细的体现。毫无疑问，这是我们科学的核心。显然，艺术与科学的应用有关，但它也关注更广泛的问题。社会和政治问题，例如系统的特定目的，需要它的需求，实现它所需的资源及其实现的后果。而且，即使出于自我利益，也需要建立需要我们想要设计的结构的建筑物需求。彼得·邓肯
There are environmental, technical and commercial reasons why the increased use of lightweight aggregate for concrete should be encouraged in this country. In this paper, arguments in favour of and factors acting against the more general use of the material are examined and it is suggested that a major stumbling block is confusion between straight forward lightweight aggregate concrete suitable for most normal construction and the more exotic materials requiredfor highly specialised applications. The author proposes a new category of lightweight concrete for those mixes that behave like normal dense concrete and argues that they should be exempt from the special restrictions imposed by current Codes of Practice on reinforced lightweight concrete. Examples of the use of both types of lightweight concrete are given together with summaries of cost studies and cost evaluations. M.E.R. Little
在桁架，连接器板和相关方面进行的相当长的讨论使H. J. Andrews先生在辩护中做出了相当积极的反应。他写道：我觉得现在是时候回应您专栏中引用的一些荒谬的“查询，评论，信件和好奇心”，以及最近加入托梁衣架（1977年9月））。Verulam
